Metadata api create entity in workspace custom app (#15911)

# Introduction
Cleaner and fewer scope version of
https://github.com/twentyhq/twenty/pull/15745 ( removed sync-metadata
hack through, too ambitious migration and upgrade )

Please note that this PR won't have any interaction with the existing
sync-metadata
Which mean that the sync metadata does not update the standard entities
applicationId and universalIdentifier, and it won't we will deprecate it
on favor of a workspace migration aka twenty-standard app installation

## API Metadata
Any operation going through the api metadata nows automatically scope
the related entity to the workspace custom application instance. (
optionally passing an applicationId to allow current hacky implem of app
sync service )

We need to either ignore the tests or remove the cli status check from
the blocking status badges for a PR to be merged

## New workspace
Already handled in previous
https://github.com/twentyhq/twenty/pull/15625, when a workspace is
created it gets created a twenty standard and custom workspace instance

All his views and permissions will be prefilled to the its twenty
standard app instance with a specific universalIdentifier

## New universalIdentifier
At the contrary as before with standardIds, universalIdentifier are
unique for a given workspace
This means that createdAt field of both object company and opportunity
will have a unique universalIdentifier whereas they share the same
standardId

## FlatApplication
Introduced the flatApplication and cache. Will migrate existing
`MetadataName` to be `SyncableMetadataName` in a following PR

## What's next
Next we will describe a twenty standard app configuration as json that
will be used to generate a workspace migration that will be run instead
of the sync metadata, in a nutshell we aim to deprecated the sync
metadata
So we can standardize any entity to have a non nullable applicationId
and universalIdentifier

## Upgrade command
Introduced an upgrade command that will create a custom workspace
instance for any workspace that do not have one in order to align with
the new behavior when creating a new workspace
